ComSonics’ Sniffer SHADOW uses the latest technology to bring you an ultra-reliable, field-use friendly, feature packed Installer’s Signal Leakage Instrument. Single button operation limits the possibility of time consuming erroneous monitoring. SHADOW is either ON or OFF. It cannot be mistuned and yet allows the flexibility for selecting a new frequency if needed. ComSonics’ exclusive Leakage Signal Validation feature saves time and money by helping the user to quickly decide whether or not the signal observed at any moment is really the desired signal, or simply spectral noise cluttering the airwaves from a near-by appliance.

Add to that two modes of operation that conserve battery energy while always ready to sound the alarm when moved into a leakage field. A flip of SHADOW’s cover reveals the liquid crystal display, hoists the integral antenna and activates the Measurement Mode. Closing the cover restores the Monitoring Mode. In the Monitoring Mode, SHADOW’s hunger for power drops to near insignificance while maintaining a watchful vigilance.
